I have implemented Admob reward ad in my unity android game. No errors and I build the apk and run it using Android Studio.
I have successfully shown the video ad, but when I try to close the ad, the app crashes and closes. Th following error is shown in the logcat.
There is no line umber shown. How will we debug this?
E/Unity: NullReferenceException: Object reference not set to an instance of an object
